I just purchased a house and it has an above ground pool. Its pretty big with a deck built around it. When i first starting cleaning it, the hayward pool cleaner thing worked fine. Now whenever i hook it up, the psi in the filter drops to 0 and nothing works. Then when i disconnect it, it takes a little bit of fiddle with things (i really have no idea what im doing, first time owner) the jets work again. I have a Clearwater 2 filter system. Any advice, help or info would be greatly appreciated.
